Calling $response.redirect() does not send the redirect to the client immediately

$response.redirect() does not redirect immediately, it let the whole page rendering before sending the 302 response back.

Compare a page containing this macro with the #stop commented or not:

{{velocity}}
$response.sendRedirect($xwiki.getURL('Main.WebHome', 'view'))
##stop
#foreach( $cnt in [1..10000000] )
#end
{{/velocity}}
